We've been dating for 5 years now, engaged for a year. We both put on some weight, but the past year I've been very motivated to getting in shape and she hasn't been. She seems like she doesn't have any motivation for doing much asides for drinking. Whenever boozes is involved she cherps right up (she doesn't have a drinking problem).We've had a lot of discussions about our weights and our goals but at the end of the day she's putting zero effort on her end. Unfortunately with the weight her B.O has gotten worse. It's been hard for me to want to make love with her, and when we do make love I can't finish because of the B.O. I do love her as a friend/ she's an extremely sweet person. I just think we've grown apart and want different futures. I don't know how to talk to her about potentially breaking up, also I feel really guilty for feeling this way towards her. our lives are so intertwined I don't know how to split from her. Any and all advice would be greatly appreciated.
